基于区块链的农产品溯源系统
|
摘要
近年来,随着消费者对农产品质量的关注度提高,可靠、可信农产品溯源技术也日益得到重视。本文提出一种依托智慧农业的区块链溯源框架,通过融合无线传感器网络、智能前端APP、数据库以及二维码标签扫描拍照等技术,基于以太坊环境设计实现了一个农产品溯源系统。农户接入系统之后,数据采集前端将数据存储至区块链系统中,利用区块链本身具备的去中心化、不可篡改、安全加密等特点,结合后台管理数据库以及溯源二维码为消费者提供安全、可靠、真实的农产品溯源信息。系统经过实地部署和应用测试,实现了农产品从生产采摘直到消费者餐桌的全程溯源。
In recent years, with the increase of consumers' attention to the quality of agricultural products, reliable and reliable traceability technology of agricultural products has been paid more attention.This paper proposed a blockchain traceability system based on smart agriculture with the integration of wireless sensor network, intelligent front-end APP, database and the QR code label scan imaging technology. The system has realized the agricultural product traceability system based on Ethereum.After farmers access to the system, data acquisition front-end data storage to blockchain system, the use of blockchain itself has the characteristics of decentralization, tamper-resistant, security encryption, combined with the backend database management and traceability QR code to provide consumers with safe, reliable and real farm products traceability information. Meanwhile, the system can guarantee the expansibility and interactivity of blockchain and other systems. After the test of the system, it can be proved that the system can realize the product traceability from the production to the consumer's table.
